refractive index materials is possible. In response, the exibility of the design increases
by applying this strategy. is method is oen applied, but only a few publications are
known. However, a systematic study was performed by Abromavicius etal. (2007) and
Melnikaitis (2009), displaying the advantages and the challenges that are related to the
method. In the study, standard QWoT designs from Ta
